What is the structure of nucleic acids?
Structure Of Nucleic Acids. All nucleic acids share a common core chemical structure. All nucleic acids are linear polymers of nucleotides. Each individual nucleotide is composed of a nitrogenous base, a 5-carbon sugar, and a phosphate group. The chemical identity of each nucleotide is determined by its nitrogenous base.
What are the four types of nucleotides?
Molecules of DNA contain 4 kinds of nucleotides, adenine (A) cytosine (C), guanine (G) and thymine (T). Adenine and guanine are classified as purines while cytosine and thymine are classified as pyrimidines. Nucleotides join together via complementary base pair conjugation. Each nucleotide has a complementary pair that it forms bonds with. Cytosine and guanine are complementary base pairs (C-G) and adenine and thymine (A-T) are complementary. The double strands of DNA link in the middle by each nucleotide bonding with its complementary base. The particular geometric structure of DNA explains why its nucleotide bases are always in specific proportions to each other; specifically, the amount of adenine is roughly equal to the amount of thymine and the amount of cytosine is about equal to guanine.

RNA molecules function to extract this information out of DNA and physically assemble the proteins.
How does RNA polymerase work?
One the two strands are split, RNA-polymerase binds to the template strand and begins to “walk” along the strand from the 5′ to the 3′ end. As it goes along, the RNA-polymerase “builds” the mRNA by adding complementary base pairs.
Which pair of nucleotides forms a bond?

What is a Nucleic Acid?
Nucleic acids hold the information that make a lion a lion, a tree a tree, and a person a person. They are the molecules that contain all the information necessary for an organism to develop traits, carry out life functions, and reproduce. It could be argued that nucleic acids are the most important molecule within any living thing. The two main forms of nucleic acids are: DNA and RNA. Both of these types of nucleic acids hold the genetic information of living things.
How do you think of nucleic acids?
A helpful way to think of nucleic acids is that they have a similar shape to a ladder. DNA is normally coiled around itself, but, if it were stretched out, it would look like a ladder with the phosphates being the sides of the ladder, the 5-carbon sugar being where the rungs (the middle part of a ladder) connect to the sides of the ladder, and the nucleotides would be the rungs themselves. RNA has the same structure as DNA except that it is only half or one side of the ladder.
What are the nucleotides in DNA?
The nucleotides that make up DNA are adenine, cytosine, guanine, and thymine. In RNA, however, the thymine nucleotide is replaced by a uracil nucleotide. This mean RNA is made up of aden ine, cytosine, guanine, and uracil. It is the order of these nucleotides in both DNA and RNA that determine an organism's traits and the proteins that it can make.
How are DNA and RNA similar?
DNA and RNA have similar structures, but there are two main differences between these nucleic acids. The first difference is that DNA is made up of two strands of nucleic acids, while RNA is only made up of one strand. The second difference is that DNA uses the nucleotide thymine in its structure, while RNA uses the nucleotide uracil. For a clearer example of these differences look at the diagrams below.

What is the role of nucleic acids in life?
Nucleic acids are found in abundance in all living things, where they create, encode, and then store information of every living cell of every life- form on Earth. In turn, they function to transmit and express that information inside and outside the cell nucleus to the interior operations of the cell and ultimately to the next generation of each living organism. The encoded information is contained and conveyed via the nucleic acid sequence, which provides the 'ladder-step' ordering of nucleotides within the molecules of RNA and DNA. They play an especially important role in directing protein synthesis.
How does DNA differ from RNA?
One DNA or RNA molecule differs from another primarily in the sequence of nucleotides. Nucleotide sequences are of great importance in biology since they carry the ultimate instructions that encode all biological molecules, molecular assemblies, subcellular and cellular structures, organs, and organisms, and directly enable cognition, memory, and behavior ( see Genetics ). Enormous efforts have gone into the development of experimental methods to determine the nucleotide sequence of biological DNA and RNA molecules, and today hundreds of millions of nucleotides are sequenced daily at genome centers and smaller laboratories worldwide. In addition to maintaining the GenBank nucleic acid sequence database, the National Center for Biotechnology Information (NCBI, https://www.ncbi.nlm.nih.gov) provides analysis and retrieval resources for the data in GenBank and other biological data made available through the NCBI web site.

Cause
- Alzheimer's Disease is another disease caused by mutation of genes in one's DNA. Presenilin-1, Presenilin-2, and APP are three genes that are known to contribute to the onset of Alzheimer's. Further, the hereditary nature of Alzheimer's had lead researchers to study the genes that must be inherited in order to develop the disease. If a mutated gene is inherited, the likelihood of acquirin…
Overview
- Cystic Fibrosis is an inherited disease that affects the secretory glands that are responsible for producing mucus and sweat. Cystic Fibrosis can affect the pancreas, the lungs, intestines, sinuses and even sex organs. With research, the prognosis for those with Cystic Fibrosis is improving, but a much decreased life expectancy is very common.
Genetics
- While certainly not as debilitating as some other genetic diseases, color blindness is also a result of mutation of genes on DNA. This condition is more prevalent in men and exists when one is unable to distinguish between colors or to see colors in typical lighting.
Prognosis
- This genetic disease affects children most often. Infantile Tay-Sachs Disease generally commences around 6 months old, culminating in fatality by the age of four while juvenile Tay-Sachs disease starts between the ages of 2 and 10 with death occurring most often by age 15. Rarely, adult onset Tay-Sachs will begin in one's 30's or 40's; but, many times it is not fatal. After …
